“…The efficacy and specificity of the therapeutic responses of olive leaves can also be influenced by their mineral composition. In general, Na, Mg, P, K, Ca, Mn, Fe, Cu, Zn, and Pb contents are possible to find and are usually measured the most in olive leaves [ 4 , 5 ]. However, several additional mineral elements, even under residual levels, can be found and constitute a particular interest for evaluating eventual specific conditions in complementary therapy, namely Li, Si, B, Al, Cr, Co, Ni, As, Se, Rb, Sr, Mo, Cd, Sn, Sb, and Ba [ 6 , 7 ].…”

Olea europaea L. folium has been studied for its potential nutraceutical properties. Quantitative and qualitative analyses were conducted on samples of Madural, Verdeal, and Cobrançosa elementary leaves and leave sprouts (mamões) collected in the region of Valpaços, Portugal. Mineral analysis determined the measurements of the levels of several macro- and micro-elements based on ICP-MS techniques. The inorganic analysis in this work allowed us to propose olive leaf extract (OLE) from different cultivars as a viable and affordable source of mineral substrates to address disorders related to essential elements such as Na, K, Mg, Ca, Mn, Fe, and Cu deficiencies. Given the importance of the research on novel therapies, finding a suitable substrate for extracting quality amounts of mineral is a priority. The physiological influence of enzymes dependent on minerals with regard to neuroinflammatory and neurobehavioral, metabolic, cardiovascular, osteodegenerative, anti-aging, pulmonary, and immunological defense disorders might dictate the importance of further research for designing supplementation based on the nutraceutical potential of OLE of these cultivars predominant in the northern region of Portugal.

SummaryThe instant controlled pressure drop (DIC) technology represents a highly efficient and eco‐friendly process that enhances the texture of food matrices. In this study, oleaster flour (OF) was subjected to DIC treatment at varying pressures (200 and 500 kPa) and processing times (30, 60, and 120 s) for the purpose of analysing its techno‐functional, chemical, concentration of bioactive components, and structural properties. The results demonstrated statistically significant differences between the untreated and DIC‐treated OF samples (P < 0.05). The application of DIC treatment resulted in a notable enhancement in the water activity, fat, ash, SDF, bound phenolic content, and antioxidant capacity of the OF (P < 0.05). The mineral content and structural properties were analysed in two samples of OF (DIC‐treated at 200 and 500 kPa for 60 s), which were selected for their superior bioactive components in comparison to the untreated OF. The 200 and 500‐kPa 60‐s DIC treatment also enhanced the mineral (Cu, Na, Mn, Mg, P, Ca, Fe, and K) and structural properties of OF, thereby rendering it a more functional flour. The utilisation of the DIC method enhances the overall quality of the end product, resulting in a visually acceptable appearance, an extended shelf life and heightened nutritional content, thereby rendering the product more practical and convenient.

The olive tree is currently cultivated worldwide, with higher incidence in Mediterranean Basin. Its climate is highly favorable to the synthesis of phenolic compounds, stored in olive leaves; their consumption has been linked to a lower incidence of cancer and cardiovascular disorders for which the research interest upon this feature has increased in last decade. This study aimed (i) to review evidence about the importance of olive leaf extract (OLE) on human health and the physiological effect of its major compounds; (ii) to update the state of the art of studies conducted on the health and technological usage of olive leaf extract; (iii) to report potential uses of OLE in pharmaceuticals, food production, and cosmetics; and (iv) to prospect the future of clinical applications of OLE from diverse cultivars, especially in metabolic inflammatory conditions such as polycystic ovary syndrome (PCOS). Overall, cultivars richer in TPC, including TFC, αT, omega-3 and omega-9, present a main research target for supplementation alone or in conjunction with vitaminic compounds, due to their nutraceutical value in metabolic disorders, chronic inflammatory diseases, and anti-aging treatments, whereas cultivars with less water content might be useful as substrates for food preservation. With regard to future prospects, it would be of great interest to clarify the specific mechanisms underlying the beneficial effects of OLE on neuro-immune and cardiovascular health to design safer and healthier nature-based medicine for a wide array of costly and highly prevalent chronic diseases, such as inflammatory and metabolic-related syndromes, namely, PCOS.
